Trust has a problem of root. You cannot exactly trust even your parents these days. They are more often wrong than not. Grandparents, even more so. Even society is shown to be untrustworthy, and the social processes of science. Thus some reactionaries want to replace trust with authority. Or markets, which is another name for social proof, but with much less transparency. Ultimately the other parts of trust are verification and reputation, which are both not unassailable. (Sybil style attacks, bribery, institutional and social biases.) But, our saving grace might be simpler: cooperation without trust is possible and might be as efficient if things get bad enough.
